June Moon Phases and Eclipses

What's in the Sky June 2020 Astronomy Events - 1

June 4 - Mercury 

The planet Mercury reaches greatest eastern elongation of 23.6 degrees from the Sun. Look for the planet low in the western sky just after sunset.

June 5 - Full Moon

This phase occurs at 19:12 UTC. This full moon was known by early Native American tribes as the Strawberry Moon because it signaled the time of year to gather ripening fruit.

June 5 - Penumbral Lunar Eclipse

A penumbral lunar eclipse occurs when the Moon passes through the Earth's partial shadow, or penumbra. The Moon will darken slightly but not completely. The eclipse will be visible throughout most of Europe, Africa, Asia, Australia, the Indian Ocean, and Australia.

June 20 - June Solstice

The June solstice occurs at 21:43 UTC. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer.

This is the first day of summer (summer solstice) in the Northern Hemisphere and the first day of winter (winter solstice) in the Southern Hemisphere.

June 21 - New Moon

Darker skies mean clearer astrophotos! This is the best time of the month to observe faint objects such as galaxies and star clusters. 

June 21 - Annular Solar Eclipse

An annular solar eclipse occurs when the Moon is too far away from the Earth to completely cover the Sun. A ring of light will display around the darkened Moon but the Sun’s corona will not be visible.

The path of the eclipse will begin in central Africa and travel through Saudi Arabia, northern India, and southern China before ending in the Pacific Ocean. A partial eclipse will be visible throughout most of eastern Africa, the Middle East, and southern Asia.
